b42297ba81 rockchip: Set default LNX_KRNL_IMG_TEXT_OFFSET_BASE to SYS_TEXT_BASE
U-Boot can be chainloaded from vendor firmware on ARM64 chromebooks from
a GPT partition (roughly the same as in doc/chromium/chainload.rst), but
an appropriate image header must be built-in to the U-Boot binary by
enabling LINUX_KERNEL_IMAGE_HEADER.

This header has a field for an image load offset from 2MiB alignment
which must also be customized through LNX_KRNL_IMG_TEXT_OFFSET_BASE.
Set it equal to SYS_TEXT_BASE by default for Rockchip boards, which
happens to make this offset zero and works fine on chromebook_kevin
both for chainloading and bare-metal use.

6d36e92d28 rockchip: rk3399: Add support for chromebook_kevin
Add support for Kevin, an RK3399-based convertible chromebook that is
very similar to Bob. This patch is mostly based on existing support for
Bob, with only minor changes for Kevin-specific things.

Unlike other Gru boards, coreboot sets Kevin's center logic to 925 mV,
so adjust it here in the dts as well. The rk3399-gru-kevin devicetree
has an unknown event code reference which has to be defined, set it
to the Linux counterpart. The new defconfig is copied from Bob with the
diffconfig:

     DEFAULT_DEVICE_TREE "rk3399-gru-bob" -> "rk3399-gru-kevin"
     DEFAULT_FDT_FILE "rockchip/rk3399-gru-bob.dtb" -> "rockchip/rk3399-gru-kevin.dtb"
     VIDEO_ROCKCHIP_MAX_XRES 1280 -> 2400
     VIDEO_ROCKCHIP_MAX_YRES 800 -> 1600
    +TARGET_CHROMEBOOK_KEVIN y

With this Kevin can boot from SPI flash to a usable U-Boot prompt on the
display with the keyboard working, but cannot boot into Linux for
unknown reasons.

eMMC starts in a working state but fails to re-init, microSD card works
but at a lower-than-expected speed, USB works but causes a hang on
de-init. There are known workarounds to solve eMMC and USB issues.

e4015661c3 rockchip: bob: Enable more configs
This patch enables some configs that should be working on the Bob board,
based on what is observed to work on the Kevin board.

The Bob board uses an Embedded DisplayPort panel compatible with the
simple panel and Rockchip eDP drivers. Its backlight is controlled by
the Chromium OS Embedded Controller Pulse Width Modulator. Enable these
for the board.

Also set VIDEO_ROCKCHIP_MAX_{XRES,YRES} to 1280x800, the resolution of
its panel. This had to be done for the Kevin board, but it's untested if
this is actually necessary for Bob.

The Rockchip video driver needs to assert/deassert some resets, so also
enable the reset controller. RESET_ROCKCHIP defaults to y for this board
when DM_RESET=y, so it's enough to set that.

The Bob board has two USB 3.0 Type-C ports and one USB 2.0 Type-A port
on its right side. Enable the configs relevant to USB devices so these
can be used. This is despite a known issue with RK3399 boards where USB
de-init causes a hang, as there is a known workaround.

Some other rk3399-based devices enable support for the SoC's random
number generator in commit a475bef534 ("configs: rk3399: enable rng on
firefly/rock960/rockpro64"), as it can provide a KASLR seed when booting
using UEFI. Enable it for Bob as well.

The default misc_init_r() for Rockchip boards sets cpuid and ethernet
MAC address based on e-fuse block. A previous patch extends this on Gru
boards to set registers related to SoC IO domains as is necessary on
these boards. Enable this function and configs for it on Bob.

The microSD card slot on this board (and others based on Gru) is
connected to a GPIO controlled regulator (ppvar-sd-card-io), which must
be operable by U-Boot. Enable the relevant config option to allow this.

Bob boards also use the Winbond W25Q64DW SPI flash chip, enable support
for Winbond SPI flash chips in the board config so U-Boot can boot with
this chip.

8ba1ade3f8 rockchip: gru: Add more devicetree settings
This adds some devicetree settings for the Gru-based boards, based on
what works on a Kevin board.

Gru-based boards usually have an 8MiB SPI flash chip and boot from it.
Make the u-boot.rom file intended to be flashed on it match its size.
Add properties for booting from SPI, and only try to boot from SPI as
MMC and SD card don't seem to work in SPL yet.

The Chromium OS EC needs a delay between transactions so it can get
itself ready. Also it currently uses a non-standard way of specifying
the interrupt. Add these so that the EC works reliably.

The Rockchip Embedded DisplayPort driver is looking for a rockchip,panel
property to find the panel it should work on. Add the property for the
Gru-based boards.

The U-Boot GPIO controlled regulator driver only considers the
"enable-gpios" devicetree property, not the singular "enable-gpio" one.
Some devicetree source files have the singular form as they were added
to Linux kernel when it used that form, and imported to U-Boot as is.
Fix one instance of this in the Gru boards' devicetree to the form that
works in U-Boot.

The PWM controlled regulator driver complains that there is no init
voltage set for a regulator it drives, though it's not clear which one.
Set them all to the voltage levels coreboot sets them: 900 mV.

The RK3399 SoC needs to know the voltage level that some supplies
provides, including one fixed 1.8V audio-related regulator. Although
this synchronization is currently statically done in the board init
functions, a not-so-hypothetical driver that does this dynamically would
query the regulator only to get -ENODATA and be confused. Make sure
U-Boot knows this supply is at 1.8V by setting its limits to that.

Most of this is a reapplication of commit 08c85b57a5 ("rockchip: gru:
Add extra device-tree settings") whose changes were removed during a
sync with Linux at commit 167efc2c7a ("arm64: dts: rk3399: Sync
v5.7-rc1 from Linux"). Apply things to rk3399-gru-u-boot.dtsi instead so
they don't get lost again.

c48021d184 rockchip: sdhci: Add HS400 Enhanced Strobe support for RK3568
On RK3568, a register bit must be set to enable Enhanced Strobe.
However, it appears that the address of this register may differ from
vendor to vendor and should be read from the underlying MMC IP. Let the
Rockchip SDHCI driver read this address and set the relevant bit when
Enhanced Strobe configuration is requested.

The IP uses a custom mode select value (0x7) for HS400, use that instead
of the common but non-standard SDHCI_CTRL_HS400 value (0x5). Also add
some necessary DLL_STRBIN and DLL_TXCLK configuration for HS400.

Additionally, a bit signifying that the connected hardware is an eMMC
chip must be set to enable Data Strobe for HS400 and HS400ES modes. Also
make the driver set this bit as appropriate.

This is partly ported from Linux's Synopsys DWC MSHC driver which
happens to be the underlying IP. (drivers/mmc/host/sdhci-of-dwcmshc.c in
Linux tree).

0f3466f52f mmc: xenon_sdhci: remove wait_dat0 SDHCI OP
Generic SDHCI driver received support for checking the busy status by
polling the DAT[0] level instead of waiting for the worst MMC switch time.

Unfortunately, it appears that this does not work for Xenon controllers
despite being a part of the standard SDHCI registers and the Armada 3720
datasheet itself telling that BIT(20) is useful for detecting the DAT[0]
busy signal.

I have tried increasing the timeout value, but I have newer managed to
catch DAT_LEVEL bits change from 0 at all.

This issue appears to hit most if not all SoC-s supported by Xenon driver,
at least A3720, A8040 and CN9130 have non working eMMC currently.

So, until a better solution is found drop the wait_dat0 OP for Xenon.
I was able to only test it on A3720, but it should work for others as well.

925f6900c8 mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON when necessary
After commit f132aab403 ("Revert "mmc: fsl_esdhc_imx: use
VENDORSPEC_FRC_SDCLK_ON to control card clock output""), it
involve issue in mmc_switch_voltage(), because of the special
design of usdhc.

For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN,
these are reserved bits(Though RM contain the definition of these bits,
but actually internal IC logic do not implement, already confirm with
IC team). Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the card
clock output. Here is the definition of this bit in RM:

[8] FRC_SDCLK_ON
Force CLK output active
Do not set this bit to 1 unless it is necessary. Also, make sure that
this bit is cleared when uSDHC’s clock is about to be changed (frequency
change, clock source change, or delay chain tuning).
0b - CLK active or inactive is fully controlled by the hardware.
1b - Force CLK active

In default, the FRC_SDCLK_ON is 0. This means, when there is no command
or data transfer on bus, hardware will gate off the card clock. But in
some case, we need the card clock keep on. Take IO voltage 1.8v switch
as example, after IO voltage change to 1.8v, spec require gate off the
card clock for 5ms, and gate on the clock back, once detect the card
clock on, then the card will draw the dat0 to high immediately. If there
is not clock gate off/on behavior, some card will keep the dat0 to low
level. This is the reason we fail in mmc_switch_voltage().

To fix this issue, and concern that this is only the fsl usdhc hardware
design limitation, set the bit FRC_SDCLK_ON in the beginning of the
wait_dat0() and clear it in the end. To make sure the 1.8v IO voltage
switch process align with SD specification.

For standard tuning process, usdhc specification also require the card
clock keep on, so also add these behavior in fsl_esdhc_execute_tuning().

351729ca44 arm: mvebu: dts: turris_mox: fix non-working network / MDIO
Commit 0934dddc64 ("arm: a37xx: Update DTS files to version from
upstream Linux kernel") ported Linux's device-tree files for Armada 3720
SOCs. This broke network on Turris MOX, because the SOC's MDIO bus in
U-Boot currently isn't probed via DM as it's own device, but is
registered as part of mvneta's driver, which means that pinctrl
definitions are not parsed for the MDIO bus node. Also mvneta driver
does not consider "phy-handle" property, only "phy".

For now, fix this by adding armada-3720-turris-mox-u-boot.dtsi file
returning the MDIO to how it was defined previously.

A better solution (using proper mvmdio DM driver) is being work on, but
will need testing on various boards, and we need the bug fixed now for
the upcoming release.

bae4d9fbd9 spi: dw: Actually mask interrupts
The designware spi driver unconditionally uses polling.

The comment to spi_hw_init() also states that the function should disable
interrupts.

According to the DesignWare DW_apb_ssi Databook, value 0xff in IMR enables
all interrupts. Since we want to mask all interrupts write 0x0 instead.

On the canaan k210 board, pressing the reset button twice to reset the
board will run u-boot. If u-boot boots Linux without having SPI interrupts
masked, Linux will hang as soon as interrupts are enabled, because of an
interrupt storm.

Properly masking the SPI interrupts in u-boot allows us to successfully
boot Linux, even after resetting the board.

The Canaan Kendryte K210 SoC DW apb_ssi v4 spi controller is documented
to have a 32 word deep TX and RX FIFO, which spi_hw_init() detects.
However, when the RX FIFO is filled up to 32 entries (RXFLR = 32), an
RX FIFO overrun error occurs. Avoid this problem by force setting
fifo_len to 31.

530f29cba5 k210: dts: align plic node with Linux
The Linux PLIC interrupt-controller driver actually initializes the hart
context registers in the PLIC driver exactly in the same order as
specified in the interrupts-extended device tree property. See the device
tree binding [1].

The ordering of the interrupts is therefore essential in order to
configure the PLIC correctly.

Fix the order so that we will have sane IRQ behavior when booting Linux
with the u-boot device tree.
